Self-organization of silver nanoparticles forming on chemical reduction to give monodisperse spheres

It was found possible to produce monodisperse spherical silver particles using K–Na-tartrate as the reductant for Ag+ in the presence of gelatin. It was shown that the silver spheres form in the process of spontaneous self-organization of 10–15 nm-sized primary particles. The conditions making it possible to control the sizes of the monodisperse spheres in the range from 150 nm to 1.5 μm were specified.
